PIvoTED AND sLIDING fw'mnow sass.)-

Application led January 16, 1926. Serial No. 81,654.

My invention relates to a window sash and is intended particularly to facilitate wash'- ing the glass of the sash. i

The purpose of my invention 1s to provide a pi'voted window sash Within a normal sliding sash so that the pivoted sash may be reversed in position for washing purposes.

` A further purpose is to mount the glass of a window directly in a pivoted sash carried by a sliding sash and to protect the joint between the pivoted sash and its mount by a vent frame.

Further purposes will appear in the specification and in the claims.

I have preferred to illustrate my lnvention by but one main form, with slight modiflcations, selecting a form which 1s practical, efficient and inexpensive and which at the same time well illustrates the principles of my invention.

Describing the figures of the drawingf Figure 1 is an inside elevation of a window frame in which are located two of my sashes. y l

Figures 2 and 3 are sections of Figure l upon lines 2 2 and 3 3 respectively.

Figures 4 and 5 are a fragmentary 'inside elevation and a section upon line 5-5 thereof 30 showing a modification.

Figures 5a and 5b are fragmentary. sections corresponding gnerally with F1gure 5 but showing a further slight modification.

Figure 6 is a fragmentary enlarged section of Figure 3.

In the drawings similar numerals indicate like parts. l v

My invention is intended to relieve the difficulties and dangers attendant upon the Washing of windows in existing sliding sashes where the windows cannot be reached from 'the ground. Itavoids the necessity for leaning out of thef window to clean the glass and permits cleaning from the inside free from interference by weather 'condi tions and without chilling of. the room durin the cleaning.

I show a casing 7 provided with the normal sash channels 8 and 9 between the outer and inner guide strips 10 and 11 and the middle guide strip 12. e

Within these guides fit the sliding sashes `13 and 14 which perform the saine function and bear the same relation to the casing as the normal sliding sashes in any window.

Within the sliding Asashes I provide openi ings 15, 16 within which are located pivots 17, 18l shown at ythe middle of the top and bottom of the openings in Figures 1--3 and at the middle of the sides in Figures 5 and 6. These support inner pivoted sashes 19 and 20 in which the glass 21 is secured at 2:2. So far as described and as best seen in Figures 1-5, this leaves the pivo'ted sashes free to turn upon their axes so as to reverse the sashes and to make both sides of the glass readily accessible for cleaning. lf the` pivots be central-whether they be mounted upon the fixed or movable parts-the inner and -outer faces 23 and 24 of the pivoted sashes will align equally with the sliding sashes making the pivot sashes interchangeable in their two positions except for the placing and fastening of t-he glass. On the other hand deliberate eccentric mounting of the pivot will prevent complete turning of the sashes and thus ensure that the intended outside face of the glass is always directed outwardly when the sashes are closed. The outer faces of the sashes are slightly curved.

Whatever the fact as to the pivoted saslies ahgning with the sliding sashes' in one position only or in both positions, the cracks `25 between the pivoted sashes and the surrounding sliding sashes can be closed quickly and completely by vent frames 26 which ft against 'the inner sides of the pivoted sashes and also against the inwardly directed faces of the sliding sashes, closing ofl' the crack between.

The vent frames may be fastened in position Within the sliding sashes by any con- Venient means for which I have shown snap buttons 27 in the one and openings 28 in the other. rIhe vent frames are provided with hand engaging devices 29.

My` invention is equally adapt-ed to upper and lower sashes and applies regardless of the size or shape of the sashes.

The form shownlin Figures 4 :md5 differs fromthat of Figures 1-3 not only in having horizontal pivoting for the swinging sashes, but also in recessing the edges of the sliding sashes so as to provide for flanges 30 upon the vent frames which cover over and additionally protect the cracks 25 between the pivoted sashes and the sliding sashes, re-

fuirinvr air leakage to follow a tortuous )assage as distinguished from a direct passage through. This fiauge and recess construction is carried throughout all four outer edges adjacent thc inner faces of the saslies. .\t the division line between the upper and lower sashes this portion 3l) upon the vent Jframe for the upper sash. can easily be fitted into t-lie position shown in Figure 5 by sliding it in diagonally from above.

In the structure seen in Figures 5 and 5" the swinging pivoted sashes are grooved to provide for a shoulder 3l upon the outside of one edge and upon the inside of the other edge of the adjacent sliding sashes, protecting against leakage through the cracks 25 though preventing completion of swing'- ing movement of the sashes throughout the 360. Corresponding ribs and grooves upon the outside and inside respectively are contemplated at the top and bottom so as to seal in this manner throughout a large part of' the distance from the respective sash sides to the pivot.

Normally the vent frame is in position as shown in the figures and each tilting sash lies as seen in Figure 2. The Window-panes are cleaned upon their inside faces as usual. When the outer faces are to be cleaned the vent frames are removed and the pivoted sashes are turned to face the outer faces inwardly for cleaning. They are then again turned to the position shown iii Figures 2 and 5 and the veut frames are replaced in position.

My invention does not interfere with the use in the sliding sashes of such refinements as overlapping of one sash With respect to the other as by flanges 32, but adds a benefitiiot present with the sliding sashes.

It will be obvious that the vent frames may be withdrawn in warmer weather giving theadvantage of swinging the tilting sashes instead ot' lifting or lowering the sliding sashes securing substantially entire opening for each window.

In view of my disclosure other means of .securing all or a part of' my invention di'ering from it to meet special difficulties, to satisfy a whim or merely to avoid direct copying will occur to those skilled in the art and it is my purpose therefore, to include herein all modifications and changes which come Within the reasonable spirit and scope of' my claims.

Y Having thus described my invention, What 'I claim as new and desire to secure by Letters Patent is 1. A sliding window sash, in combination with a pivoted Window sash carried by it and sealing it transversely and a removable vent frame sealing the oint between them.

2. A sliding Window sash having an opening and interiorly recessed to provide a shoulder, in combination with a sash pivoted in the opening and a Wholly removable vent frame fitting against the shoulder and sealing against leakage of air between the pivoted sash and the sliding sash.

3. A sliding sash having an opening in it and a recess forming a shoulder adjacent the recess, in combination With a pivoted sash within the opening and noi-- mally having its inner face depressed in the sliding sash and a vent frame fitting against the inner face of the pivoted sash and the shoulder and readily movable from set position to permit reversal of the pivoted sash.
